Bringing this back to top. In another post somebody asked if the s-mini clip might fit the UF-2100 and variants and didn't get an answer . . somebody has to have both of those lights???
Big service if some of you will take some clips off your lights and post the inside diameter if they have a ring, or the outside diameter of the part of the body for clip on versions where the clip rides.
PS - I'm still searching to fit a specific niche (diameter under 22 mm and bright) right now and the light I get must have a clip . . preferably something that allows deep carry so that 20+/-mm of the light is above the clip. https://budgetlightforum.com/t/-/8157
